CVE-2022-3222Public exploitNetwork attack vector

Process crash via unbounded BIFS expression recursion

Published Sep 15, 2022 · Updated Aug 3, 2024

Uncontrolled recursion in GPAC before 2.1.0-DEV allows remote attackers to crash MP4Box through a crafted media file. The BIFS script decoder's SFS_Expression routine recursively parses nested expressions without tracking depth, exhausting the process stack. A user must direct MP4Box to process the attacker-supplied file; successful exploitation terminates that process without reported data disclosure or modification.
